You’ve probably seen the posts. They’re usually shared in Facebook groups or on old-school health forums by someone’s well-meaning aunt. They claim that a simple mixture of baking soda and molasses for cancer is the "hidden cure" that Big Pharma doesn’t want you to know about. It sounds perfect, doesn't it? It’s cheap. It’s sitting in your kitchen cabinet right now. It feels like a David-vs-Goliath win against a terrifying disease.
But honestly, the reality is a lot messier than a viral post.
When people talk about using sodium bicarbonate (baking soda) and blackstrap molasses to fight tumors, they aren't just making it up out of thin air. There is a kernel of scientific logic buried under layers of dangerous oversimplification. This theory—often called the "Sircus Method" or the "Kelley Protocol" in various alt-health circles—suggests that you can basically trick cancer cells into eating their own destruction. It’s a bold claim.
Let’s get into the weeds of why people believe this, what the lab results actually show, and why drinking a slurry of alkaline powder might not be the miracle some claim it to be.
The Theory of the "Trojan Horse"
The whole idea behind using baking soda and molasses for cancer relies on something called the Warburg Effect. Back in the 1920s, Otto Warburg noticed that cancer cells are sugar hogs. They consume glucose at a much higher rate than normal cells. They’re essentially fuel-hungry engines that ferment sugar to produce energy, even when oxygen is available.
Here is the "logic" used by proponents like Vernon Johnston, who popularized this specific protocol years ago:
The molasses acts as the bait. Since cancer cells love sugar, they supposedly rush to gulp down the molasses. But, because the molasses is bonded with alkaline baking soda, the cancer cell accidentally swallows the "poison." The theory suggests that the sudden shift in pH—moving from acidic to alkaline—shocks the cancer cell and kills it.
It sounds like a clever military maneuver. A Trojan Horse for your bloodstream.
The problem? Biology isn't a cartoon. Your body has an incredibly tight, rigorous system for maintaining its pH levels. Your blood must stay between 7.35 and 7.45. If it moves too far in either direction, you don't just "alkalize" your cancer—you end up in the ICU with metabolic alkalosis or acidosis. Your kidneys and lungs work 24/7 to make sure that a spoonful of baking soda doesn't drastically shift your systemic pH.
Does Baking Soda Actually Affect Tumors?
Surprisingly, there is real research on sodium bicarbonate and cancer. It just doesn't look like what the influencers say it looks like.
Researchers at the H. Lee Moffitt Cancer Center and the University of Arizona have looked into "buffer therapy." They found that the area immediately surrounding a tumor (the microenvironment) is often highly acidic. This acidity helps the cancer grow, protects it from the immune system, and even makes it more resistant to chemotherapy.
In mouse studies, researchers like Dr. Robert Gillies have shown that oral sodium bicarbonate can increase the pH of the tumor's microenvironment. This didn't necessarily "kill" the cancer on its own, but it did seem to:
- Slow down the formation of new metastases (the spread of cancer).
- Make certain chemotherapy drugs more effective.
- Keep the tumor from invading nearby healthy tissue as aggressively.
But—and this is a huge "but"—those were mice. And they were given massive, controlled doses that are hard to replicate safely in humans without professional monitoring. Also, the molasses? Science hasn't found any evidence that it acts as a "delivery vehicle." In fact, giving a tumor more sugar is generally considered a bad move in most oncological circles.
The Risks Nobody Mentions on Social Media
We think of baking soda as harmless because we put it in cookies. It’s not.

If you start slamming high doses of baking soda and molasses for cancer every day, you’re messing with your electrolytes. Sodium bicarbonate is, obviously, full of sodium. This can skyrocket your blood pressure. It can cause swelling (edema). Even worse, it can deplete your potassium.
Low potassium (hypokalemia) is no joke. It can lead to heart arrhythmias and muscle weakness.
Then there’s the stomach issue. Your stomach is supposed to be acidic. That acid is there to digest food and kill pathogens. By neutralizing that acid constantly, you’re opening the door to digestive issues and potentially harmful bacteria. There have even been documented cases of "gastric rupture"—literally a stomach exploding—because of the massive amount of carbon dioxide gas produced when baking soda hits stomach acid. It's rare, but it's a terrifying price to pay for a "natural" remedy.
The Danger of Delay
The biggest risk isn't the baking soda itself. It's the "alternative" trap.
When someone believes a kitchen-cupboard cure is the answer, they often delay conventional treatments like surgery, immunotherapy, or targeted radiation. In the world of oncology, time is the only currency that matters. A tumor that was treatable in Stage II can become terminal by the time someone realizes the molasses protocol isn't working six months later.
What the Experts Say
Most oncologists will tell you that while the concept of pH manipulation is an interesting area of research, the DIY version is dangerous.
Dr. Barrie Cassileth, the founder of the Integrative Medicine Service at Memorial Sloan Kettering, was famously vocal about the dangers of "alkaline diets" for cancer. She pointed out that there is zero clinical evidence that eating or drinking alkaline substances changes the internal pH of a tumor in a way that cures the disease.
Basically, you can’t "starve" or "alkalize" cancer out of existence with a grocery store run.
Why Do People Still Swear By It?
Anecdotes are powerful. You’ll find videos of people claiming they were "sent home to die" and cured themselves with this mixture.
Placebo is one hell of a drug, but there's also the "co-treatment" factor. Many people who try these alternative methods are also receiving some form of conventional care, or they have a slow-growing type of cancer that may have regressed for other reasons. We also have to face the grim reality that the people for whom it didn't work aren't around to post their results on YouTube. It's a classic case of survivorship bias.
Actionable Steps for Patients
If you are considering baking soda and molasses for cancer, don't do it in a vacuum. You need to be smart about how you integrate "natural" ideas with proven science.
- Talk to an Integrative Oncologist: These are MDs who specialize in combining conventional treatment with evidence-based supplements. They can tell you if baking soda will interfere with your specific chemo drugs.
- Monitor Your Bloodwork: If you’re dead-set on trying an alkaline approach, you must have a doctor monitor your potassium and sodium levels. Don't guess.
- Focus on Diet, Not Just "Magic" Mixtures: Instead of a molasses slurry, focus on a high-fiber, plant-heavy diet that naturally supports your body’s detoxification pathways without causing a pH crisis.
- Check the pH of your urine? Some people use pH strips to test their urine. Just remember: your urine pH tells you what your body is getting rid of, not the pH of your internal organs or your tumor.
The allure of a simple cure is strong, especially when you’re scared. But cancer is a complex, cellular shapeshifter. It requires a strategy that is just as sophisticated as the disease itself. Baking soda might have a future role as a "support player" in clinical settings to help drugs work better, but as a standalone cure? The evidence just isn't there.

Stay skeptical. Stay informed. And always, always talk to your medical team before turning your kitchen into a laboratory.
Next Steps for Evidence-Based Support:
- Request a Nutrition Consultation: Ask your oncology clinic for a referral to a Registered Dietitian (RD) who specializes in cancer.
- Screen for Clinical Trials: Look into trials involving "buffer therapy" or "pH-sensing nanomedicines" if you are interested in the science of acidity and cancer.
- Audit Your Supplements: Bring a full list of everything you're taking—including baking soda—to your next appointment to check for dangerous drug interactions.
